Report on compilation and ranking of exposure to workers and members of the public by type of industry

Compilation and evaluation of exposure to workers and members of the public by type of industry in countries participating in the TENORMHARM project was carried out by ranking of the impact of residues appearing at certain branches of industry in terms of the potential or real radiation risk. In order to prepare the ranking scheme, a simply algorithm of classification was agreed among the members of the consortium.

As the national reports demonstrate the possible levels of dose, the amount of material, residuals and waste, number of the members of the public of concern and, the level and variability of specific activities differ considerably between the participating countries as well as between single plants of each special TENORM branch. The greatest amount of residuals results from mining and combustion of coal in all countries.

On the other hand, from the heaped up or re-used waste rock material and hard coal as well as lignite combustion products (CCP) only a minor part contains naturally occurring radionuclides with enhanced concentrations (> 200Bq/kg) but the total number of potentially influenced person is very large due to common use of such waste, i.e. as construction materials.

Nevertheless, mining and milling activities may lead to higher contaminated residues as a consequence of discharging waters with enhanced concentration of radium isotopes or sludge from such water treatment plants. The most important is the first situation because such water can cause uncontrolled contamination of ponds or rivers banks. Additionally the contamination can be spread out by flood so that the number of affected persons is difficult to asses.

In comparison, high specific activities of naturally occurring radionuclides in smaller amounts were identified for oil and gas exploitation, ore melting and processing of mineral sands. Such waste materials are not very common and the range of their occurrence is usually limited to the territory of a plant where they have been processed, i.e. only workers could be exposed.
